I have a few Dataflows that are using the Power BI Dataflows (Legacy) connector which are giving authentication error even after signing in with OAuth. However, if I swtich those over to new Dataflows (i.e. the Power platforms data connector) the connection seems to start working again.
The issue is I have several queries using the Legacy connector. If my assumption is correct and the legacy connector has an issue, is there anyway to resolve this?
**Edit, when using the Legacy connector, this is the error message I get on refresh
Data source credentials are missing or invalid. Please update the credentials for PowerBI in dataflows settings page and try again. [Path: PowerBI].</ccon> Request ID: 99381b46-1d05-47b7-8a35-42da9a0dd1f6 Activity ID: 744f6ced-14de-4f06-852b-59dba594ff31
The query that's failing has Power BI Dataflow (legacy) as source. If I were to switch this to the power platform connector, the error goes away. You can actually scratch this as I am working with Microsoft Support on this issue.
